STAMPING MACHINE Filed Dec. 29, 1954 r en INVENTOR 504 [/F5/ 72 BY kATTORNEY Patented June 25, 1935 STAMPING MACHINE Sol Lifsitz, Detroit,Mich, assignor of one-half 'to Israel M. Hertz, Detroit, Mich.

Application December 29, 1934, Serial No. 759,633 11 Claims. 01. 101-37) The present invention pertains to the marking of pieces of laundry,particularly such pieces as are rented by a laundry supply service andpieces owned by hotels and other institutions. At the present time, themarking or stamping of the pieces is done by hand, probably because amechanical devicepresents several difficulties. First, a piece oflaundry must be re-stamped one or more times before it is discarded, andnot all the pieces in a wash require stamping. Again, a timed mechanicalmarker would require a complicated adjusting mechanism, inasmuch as thepieces handled in different batches, or even in the same batch, at timesare not of uniform 5 length. w

The principal object of the present invention is to provide a stampingdevice which is mechanically driven but manually controlled, in order toprovide for the irregularities previously mentioned. A second but veryimportant object is to make possible the stamping of the laundry withoutthe expenditure of an appreciable amount of extra time, by causing thisoperation to be performed during the handling of the work in some otherlaundering process.

It is well known that the ink adheres to the cloth more firmly if thestamped area is given a heat treatment immediately after the ink isapplied. In this connection, still another object of the invention is tofurnish this heat treatment.

In order to accomplish these objects, the invention embodies a stampingroller journalled in a suitable bracket carried bythe frame work of aconventional laundry machinein which the work 35 is ordinarily subjectedto heat, such as a mangle. The roller is mounted close to the conveyorwhich feeds the machine and is so positioned that parts of its peripheryare adapted for tractive engagement with the work carried by theconveyor. Intervening parts of the roller are notched or recessed, andwhen any one of these parts is disposed immediately over the box, theroller does not turn. The roller assembly carries push pieces withinconvenient reach of the operator while the latter is feeding a piece ofwork to the machine. If the piece is to be stamped, the operator pushesthe push piece to'bring a tractive part of the roller into engagementwith the work, whereupon the roller turns and brings the stamp properinto engagement with the work. When the next recessed part of the rollercomes to a-position immediately over the work, the tractive engagementis broken and the roller stops turning. Thus, the work is stamped onlywhen the operator actuates one of the push pieces.

The invention is fully disclosed by way of ex-' ample in the followingdescription and in the ac-' companying drawing in which.

Figure l is a side elevation of the device;

Reference to these views will now be made by.

use of like characters which are employed to.

designate corresponding parts throughout.

In Figure l, the numeral indicates a part of the frame of a conventionallaundering machine, preferably one that heats the work passingtherethrough, such as a mangle. The support'for'the stamping deviceincludes two clamp pieces 2 en gaging the member 4 and held together'bybolts 3. A spring arm l is held by the. bolts, and one or more shims 5may be inserted between the arm l and the nearer member 2 if necessaryor desired. A bearing member 6 has a shank 1 formed with tapped holes 8.These holes are adapted to lie beneath slots 51 in the free end of themember 4; whereby the bearing member 6 may be secured adjustably to themember 4 by means of thumb screws l9 passed through the slots 9 andscrewed into the holes 8.

In the arms of the member 16 is journaled a shaft H to which is secureda roller [2. Beneath the roller is a flat conveyor l3 which feeds. themachine, and this conveyor rides over a table It at the roller. It willbe seen, however, in Figure 3 that the roller itself does not engage thework l5 passing through the machine. In the periphery of the roller areinserted one or more stamping members it arranged parallel to the axisof the roller and spaced from each other. The face ll of each stampingmember is at such a distance from the axis of the roller that it cancome into tractive engagement with the piece 40 i5, and each face isfurther formed to impress the work with characters represented by theletters A, B, C, D,,E, F, G in Figure 2; It is evident that when oneofthe spaces is between members I6 is disposed immediately over the work,the roller 45 does not turn. The means for bringing a stamping memberinto engagement with the work,

when and as desired, will now be described.

This means consists merely 'of one or more push pieces, corresponding tothe number of members I 6 carried by the roller l2, associated with theroller assembly and within convenient reach of the operator while'thelatter is feeding a piece of work to the machine, so that the rollerassembly may be turned to bring one of its tractive Figure 2 is afragmentary plane view thereof,

7 parts into engagement with the work. While the push pieces may becarried directly by the roller itself, a preferred construction isillustrated herein. A disk 20 is carried by the shaft II at each end ofthe roller and is the same ,cir-

cumference as the faces I! of the stamping member" IS, in order also tohave tractive engagement with the work as may be seen in Figures 1 and2.

However, the periphery of each disk is notched at 2| opposite the endsof the spaces I8 between the members IS. The notches 2i are narrowerthan a the spaces l8 and the latter'are overlapped by the unmutilatedparts 22 of the disk 2!! at the trailing side of each space l8, withreference to the direction of rotation indicated by the arrows in IFigures 1 and 3, for a purpose which will presently appear. An inkingroller- 23 is journaled in the a bracket 6', and is engaged by the facesH as the roller turns on its axis.

Finger push pieces 24 are fixed to or formed integral with the disks 20and project outward from the outer faces thereof. These members liewholly within the projected cylindrical surface embodying the stampingfaces I! or the periphery of the disks 20'. The reason for sopositioning the push pieces is to maintain them entirelyiclear ofthemo'ving work piece l5 and out of driving engagement therewith or withany other moving part of the machine. They correspond in number to thestamping member l6 carried by the roller l2;

When a space 18 and its aligned notches 2| lie immediately'over theconveyor, just before reaching the position shown in Figure 3, thestamping device is idle and can. be brought into tractive engagementwith the'work only by pushing one ofthemembers 24. These members are sopositioned that the lowermost one can conveniently be pushed by thethumb of the operator as he lays a piece of work on the conveyor 13 tobe fed to the machine. 3 A slight push brings the leading edge of anunmutilated segment of a disk 20 into engagement with the work,whereupon rotation of the roller is initiated. Because of the previouslydescribed relations of the overlapping parts 22 to the spaces I8, thestamp is applied to the work at a pre-determined distance from theentering edge of the work. This distance depends on the spacing betweennotches 2| which may be established as desired. As the work passesthrough the laundry machine, it receives a heat treatment which sets theink of the stamp.

The operator need use only one hand to start the roller, and only onedisk 20 is essential, but.

the provision" of two disks adapts the device for right handed and lefthanded operators or permits the operator to change hands from time totime.

The'shaft H is in the form of a bolt having a nut23 at one end so that aroller of a different size or with different stamps may be inserted whendesired. Similarly, the inking pad is held bya bolt 26 and nut 21 forinterchangeability. The resiliency-of the member 4 permits a stampingmachine, a shaft, aroller cylindrical surface projected from the facialcir-' 'cumference of said stamping member.
